Structure for mounting storage device and computing device

Abstract

A structure for mounting a storage device to a server and providing a fast installation and removal of a storage device includes a carrier and a chassis. The carrier includes a rotatable handle with a cam on the axis of rotation and a frame. The cam is connected to the frame. The chassis includes an immovable limiting component. With the carrier mounted in the chassis, rotation of the handle clockwise or counterclockwise pushes the carrier to move, to lock or unlock the carrier because of the limiting component resting against the cam. The structure greatly improves the convenience of the installation and removal of the storage device. A computing device is also disclosed.
